An agent with the FBI’s elite K-9 unit works with her loyal search-and-rescue Labrador to sniff out a terrorist.

FBI Agent Megan Jennings and her canine partner Hawk are an effective team. With his highly trained sense of smell, Hawk can locate bodies anywhere—living or dead. When a bomb rips apart a government building in Washington D.C., they get to work saving the survivors buried beneath the rubble.

But even as the duo are hailed as heroes, a bomber remains at large. As more bombs are detonated and the body count soars, Meg and Hawk attempt to find the pattern to a madman’s reign of terror. Soon the desperate manhunt leads them into the wilderness of West Virginia, where the lone wolf can turn the hunters into the hunted.
